'I wished she was dead': Living with my daughter's bipolar meltdowns

In a separate interview, Mr Leonard Koh, 45, recalls: "I was so shocked to see Madam Cheong sitting on the window ledge, pulling the right arm of her daughter, who was half-kneeling and half-squatting on the floor."

The technician, who is still renting a room, quickly separated the pair.

"I held on tightly to Madam Cheong because I was so worried that she may just jump."

He later called his older sister, a nurse, for help.

Madam Cheong says: "If not for Mr Koh, I dread to think what would have happened today."

Wendy admits that the same incident made her realise she has a part to play in keeping her illness under control.

She says: "I had dreams... beautiful ones... of going to university and studying to be a journalist."

But she started to suffer bouts of depression just after her A-level exams.

Says Wendy: "I don't really know what happened, but suddenly, I had these bouts of depression for no reason. I thought I was going bananas."

By the time she got her results - 3As and 2Bs - her condition had deteriorated.

"One minute, I felt on top of the world and the next, I felt utterly in despair. It got to a point where I felt like I couldn't breathe," adds Miss Wendy.

It didn't help that the self-confessed introvert did not have many friends she could confide in.

"There was only this one friend, but she started to keep a distance (from me) because she said my depression made her depressed. She didn't like that kind of feeling."

Other incidents "that were totally out of control" made it harder for Wendy.
